before or after?

I was wondering…..is it possible for the energy or spirit, or even something or message a person is fighting for to get even stronger after they transition into their next life? This may or may not sound strange, but, I remember when Christopher Reeves passed away, it seemed like his energy got stronger, as he was fighting so hard for stem cell research. Of course, in a family member it may seem that way, because we may have seen them so ill….and because of the close bond we had with them. It is probably an individual thing. curious about the thoughts of others. peace.
